ABSTRACT The properties of the bactericidal action of silver zeolite as affected by inorganic salts and ion chelators were similar to those of silver nitrate. The results suggest that the contact of the bacterial cell with silver zeolite, the consequent transfer of silver ion to the cell, and the generation of reactive oxygen species in the cell are involved in the bactericidal activity of silver zeolite.

Cellular Reactive Oxygen Species

As the powerhouse of the cell for producing adenosine triphosphate (ATP), the “energy currency” for energizing aerobic life, the mitochondrion is also a major source of cellular reactive oxygen species (ROS) production. Cutting-edge research studies over the past few years have uncovered a series of previously unrecognized fundamental biological functions carried out by mitochondrial ROS. Among them is the regulation of immunity by mitochondrial ROS signaling. (First online: Mar 13, 2021) REFERENCES Schriner SE, Linford NJ, Martin GM, Treuting P, Ogburn CE, Emond M, et al.
